The soil microbial fuel cell (SMFC) is a new device that was originally designed to generate electricity from organic matter in soil using microorganisms. Currently, SMFC based biosensors are emerging as a new and promising research direction for real-time and rapid monitoring of soil quality or soil pollution. Compared to conventional biosensors, SMFC based biosensors exhibit advantages such as low-cost, simple design, in-situ, and long-term self-powering monitoring, which makes it become attractive devices for in-situ long-term soil quality or soil pollution monitoring. Thus, this review aims to provide a comprehensive overview of SMFC based biosensors. In this review, different prototypes of SMFC based biosensors developed in recent years are introduced, the biosensing mechanisms and the roles of SMFC are highlighted, and the emerging applications of these SMFC based biosensors are discussed. Since the SMFC based biosensors are applied in open-air conditions, the effects of different environmental factors on the biosensing response are also summarized. Finally, to further expand the understanding and boost the practical application of the SMFC based biosensors, future perspectives including fundamental mechanism exploration and investigation of the full-scale application are proposed.
土壤微生物燃料电池（SMFC）是一种新型装置，最初设计用于利用微生物从土壤中的有机物中发电。目前，基于 SMFC 的生物传感器作为一种实时和快速监测土壤质量或土壤污染的新的有前途的研究方向正在出现。与传统的生物传感器相比，基于 SMFC 的生物传感器具有低成本、简单设计、原位和长期自供电监测等优势，使其成为原位长期土壤质量或土壤污染监测的有吸引力的设备。因此，本综述旨在提供对基于 SMFC 的生物传感器的全面概述。在本综述中，介绍了近年来开发的不同原型的基于 SMFC 的生物传感器，强调了生物传感机制和 SMFC 的作用，并讨论了这些基于 SMFC 的生物传感器的新兴应用。由于基于 SMFC 的生物传感器应用于露天条件下，因此还总结了不同环境因素对生物传感响应的影响。最后，为了进一步加深对基于 SMFC 的生物传感器的理解并推动其实际应用，提出了包括基础机制探索和全面应用研究在内的未来展望。
